Patented May 9, 1944 UNITED sTATEs PATENT OFFICE 2,348,273 LEAi; MENDER Luther Martin Yaggy, Bag'ley, Minn. Application September 2, 1942, Serial No. 457,098

1 Claim.

invention is an improvement over that described in the United States Patent No. 1,483,311, and

the main object of the present invention is to provide facilities for more readily inserting the device in place, and to prevent a member of the leak mender from falling into the boiler while eiforts are made to insert the leak mender in place. v

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawing whether within or Without the scope of the appended claim and irrespective of other specific statements as to the scope of the invention contained herein.

In the drawing:

Figure l is a side elevation of the main parts of the device; Fig. 2 is a side elevation of these main parts turned axially 90 degrees; Fig. 3 is a side elevation of the device ready for inserting; Fig. 4 is a side elevation showing the device almost completely inserted; Fig. 5 is a View partially in section showing the device completely inserted and secured to a boiler; and Fig. 6 is a face View of the inserted device looking from the inside of the boiler.

Similar numerals refer to throughout the several views.

My improved leak mender consists mainly of a screw threaded bolt, which is longitudinally divided into two members i and 2, and of a pin 3 which pivotally connects the members I and 2. Feet 4 and 5 extend each at an angle, preferably at a right angle, to the main part of the members I and 2 in opposite directions from the bolt as a whole.

To insert the mender in a leak, the leak is cut out by a suitable tool to form a larger hole similar parts 6 and the members I and 2 are spread apart so as to form, for instance, an angle of degrees, as may be seen in Fig. 3. In this position the pointed ends of the feet 4 and 5 are so close together that they can pass through the hole 6. Then the members I and 2 are brought together as illustrated in Figs. 4 and 5 whereby the device can be pushed farther into the boiler 1, until the members I and 2 are in the position shown in Fig. 5. Now a packing 8 surrounding the members I and 2 is pushed toward the boiler I and is bound in placeby means of a nut 9 and a Washer 10.

As the members I and 2 are pivotally connected to one another by the pin 3, it is impossible that one of these members can fall into the boiler while the device is inserted, which can easily happen with the device described in the United States Patent No. 1,483,311. 1

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may bemade by those skilled in the art Without departing from the spirit of the invention. It is the intention, therefore, to be limited only as indicated by the scope of the following claim.

What is claimed is:

A leak mender comprising a screw threaded bolt divided lengthwise into two members, a pin pivotally connecting said members permanently to one another, feet extending each at an angle to the main part of each of said members and in opposite directions from the bolt as a whole, a packing surrounding said members, a nut to bind said packing in place, and a washer between said nut and said packing, said pin being located adjacent said'feet and extending at right angles thereto.
